Still Waters Posted March 29, 2018 #1 Share Posted March 29, 2018 Scientists have turned their attention to investigating that most annoying of human habits - the sound made when you crack your knuckles. The characteristic pop can be explained by three mathematical equations, they say. This confirms the idea that the cracking sound is due to tiny bubbles collapsing in the fluid of the joint as the pressure changes. Surprisingly, perhaps, the phenomenon has been debated for around a century. http://www.bbc.co.uk/news/science-environment-43572709 3 Link to comment Share on other sites More sharing options...
Katniss Posted March 29, 2018 #2 Share Posted March 29, 2018 (edited) This is interesting. I'm bad about doing this and have been doing this since I was a kid. My mother use to tell me that I would get arthritis early in life if I didn't stop cracking my knuckles. Lol. I think the popping sound just annoyed her. Sorry mom - pop, pop, pop - pop, pop, pop Edited March 29, 2018 by Katniss 4 Link to comment Share on other sites More sharing options...
Hawken Posted March 29, 2018 #3 Share Posted March 29, 2018 My ankles crack more then any other joint. Link to comment Share on other sites More sharing options...
pallidin Posted March 29, 2018 #4 Share Posted March 29, 2018 Yeah. Once I find a knuckle that "cracks", I just keep doing it until it goes away and it feels better. I heard that this is not harmful at all, but, not sure. Anyone know? 1 Link to comment Share on other sites More sharing options...
Hankenhunter Posted March 30, 2018 #5 Share Posted March 30, 2018 Gawd, when I get up in the morning I sound like snack time at the Orville Reddenbacher factory. Even my old arthritic dog looks at me as if to say, "Whoa dude, sucks to be you." Hank 1 Link to comment Share on other sites More sharing options...
quasar_kid Posted March 30, 2018 #6 Share Posted March 30, 2018 I can better explain it in my own language but I'll try in English. When you crack your knuckles fluid is being released that holds the fingerbones loosely together, if you do it for years on end it can cause severe arthritis because the gap between your bones can't close properly anymore which results in your fingers being "bent".

+DieChecker Posted March 30, 2018 #7 Share Posted March 30, 2018 I've always heard it is bad for your joints, but here I am almost 50 and my fingers are still pain free.... I guess I'll keep cracking them. I also can pop my elbows, shoulders, ankles and feet bones. The elbows are particularly loud. Like a knuckle pop times three. 1 Link to comment Share on other sites More sharing options...

Neck, back, fingers, toes, ankles, knees and a weird one - my Xiphoid process. i believe that is what it is called. The little bone below the sternum.

I can crack the upper part of my sternum too, but that's due to the surgery I had a couple years back. It is not too much unless it is hurting you, I think.

I'mConvinced Posted April 3, 2018 #12 Share Posted April 3, 2018 I really had to fight hard to even read this thread. I've avoided it ever since I saw the article on the front page but today was the day. If you pop things then I hate you. I hate the sound, I hate the feeling it generates inside my head, I hate the smug looks on peoples faces while they DO IT ON PURPOSE to screw with you. Yes, I hate you all. That said, behind your hideous joint cracking craziness I'm sure you're all good people. Just please be those good people very, very far away from me . And yes, I'm Misophonic.
